5 fault codes documented
'ERROR 2' displayed — Machine too cold
The machine displays 'ERROR 2'. This safety feature activates if the machine has been exposed to cold temperatures for an extended period, disabling the heating function.
'Fill water tank' displayed — Water tank float trapped
The machine displays 'Fill water tank' even when the water tank is full. This indicates that the internal float mechanism in the water tank may be stuck.
Little or no water/steam from cappuccino frother — Blocked connector
The cappuccino frother produces little to no water or steam, and the pump sounds very quiet. This issue often points to a blockage within the frother's connector.

The grinder is operating with an unusually loud noise. This typically indicates that foreign objects have inadvertently entered the grinder mechanism.
Other 'ERROR' messages displayed — General machine fault
Any 'ERROR' message other than 'ERROR 2' is displayed on the machine. This indicates a general internal malfunction or an unspecified system error.
